Verdensrommet > Komet - Asteroide

Xenon - a colourless, odourless gas which makes up less than one billionth of the volume of Earth's atmosphere - might hold the key to answer a long-standing question about comets: did they contribute to the delivery of material to our planet when the Solar System was taking shape, some 4.6 billion years ago?

NASA's Near-Earth Object Wide-field Infrared Survey Explorer mission has released its third year of survey data, with the spacecraft discovering 97 previously unknown celestial objects in the last year.

Image data from NASA's Cassini spacecraft shows evidence that Saturn's moon Enceladus may have tipped over, reorienting itself so that terrain closer to its original equator was relocated to the poles.

Psyche, NASA's Discovery Mission to a unique metal asteroid, has been moved up one year with launch in the summer of 2022, and with a planned arrival at the main belt asteroid in 2026 -- four years earlier than the original timeline.

Scientists using NASA's Kepler space telescope identified a regular pattern in the orbits of the planets in the TRAPPIST-1 system that confirmed suspected details about the orbit of its outermost and least understood planet, TRAPPIST-1h.

11 May 2017 If you could fly a CubeSat to the Moon, what could such a tiny satellite do there? ESA posed this question - and now four proposals will be studied in more detail for possible flight over the coming decade.
